Jyong afa771dcac feat(knowledge-fs): keep query images with retrieval test history
Query images attached to a retrieval test vanished as soon as the run's
history record was selected, and were never shown again after a reload,
because nothing persisted them: the gateway dropped `queryImages` when writing
`answer_traces`, the console trace/research responses had no image field, and
the composer cleared its images on every record selection.

- knowledge-fs: add a nullable JSON `query_images` column to `answer_traces`
  (migration 0049 for postgres and tidb), persist and read it in the answer
  trace repository, and expose `queryImages` on quality trace list items.
- api: enrich trace and research task responses with
  `KnowledgeFSQueryImageResponse`, resolving file names and short-lived signed
  preview URLs only for files the acting account still owns; regenerate the
  console and service contracts.
- web: keep composer images scoped to the selected record like the query
  text, remember images per run in this session, fall back to persisted
  previews (with a labelled placeholder when the file is gone), show them in
  the result panel and as a count on history records, and carry them into
  retests.
